Abstract

Strain JC207 was isolated from a deep (265 m) sea sediment, and appeared as dark yellow colonies on agar plates with cells staining Gram-negative. Catalase, oxidase and caseinase were positive, while chitinase, gelatinase and amylase were negative. Major (>5 %) fatty acids were iso-C, anteiso-C, iso-Cω9, iso-C, iso-C 3-OH, iso-C 3-OH, iso-C and iso-CG. Strain JC207 contained phosphatidylethanolamine as the major polar lipid, with minor amounts of five unidentified lipids. A bacterial hopane derivative, diplopterol and adenosylhopane were the major hopanoids. Genomic DNA G+C content was 47.5 mol%. 16S rRNA gene sequence comparisons indicated that strain JC207 represented a member of the genus within the family of the phylum . Strain JC207 had sequence similarity with YIM-C338 (98 %), BH206 (97.6 %) and other members of the genus (<96.8 %). However, strain JC207 showed an average of 23.6±4 and 37±4 relatedness (based on DNA–DNA hybridization) with CGMCC 1.6308 ( = YIM-C338) and KCTC 12883 ( = BH206), respectively. Morphological, physiological and genotypic differences from the previously described taxa support the classification of strain JC207 as a representative of a novel species in the genus , for which the name sp. nov. is proposed. The type strain is JC207 ( = KCTC 32444 = CGMCC 1.12641).
